Amazing day, and not in a good way

wow, today absolutely blew my mind,
before i get into the story i have some things to say, Life comes at you at a thousand miles and hour, and it can change in a split second, and i am so thankful that i am here right now, and that me and all of my peers are okay, and healthy, and unharmed physically. So here's what happened:

okay well today was a normal day until 1:30 this afternoon, when our whole school went into lock down for like 4 hours!apparently this girl who goes to our school broke up with her boyfriend who is not in school, so this guy was pissed off, and the girl and her best friend knew that he had a gun on him. Well today he sent her a threatening text or something, and then came to the school with 2 of his friends, and then the next thing you know our whole school is in lock down. i was in a student council meeting, with like 16 other people, stuck in a small, small room, no windows, no nothing, and pitch blackness, like you could seriously not see your own hand in front of your face! so we stayed there, and i thought it was just a practice lock down, but we were sitting there for 40 minutes, and then school ended, so we were like wow this is real. and then the police came in the school, and they ran through the whole school, checking doors, and making sure there was no one in the halls. and then they left, and we didn't hear anything for another hour and a half.
and then they stared evacuating the school. so like another 20 minutes of that, and then they got to our room. an like busted the door open, and had their guns pointing at us, and were like "Get down on the ground, put your hands in the air!" and like Oh My God they had gun's pointing at us, it was only police, but i mean come on!
that doesn't happen to just anyone, so then we were evacuated, and got to go home, but i didn't get home till 6, and being at school at 8:30!! crazy but no one was hurt, and they ended up not finding the guys who were in the school.
but i am just so thankful that no one was hurt. But i am still in shock, i can't believe that happened to us, it still hasn't hit yet!While all of this was happening, i was stuck in that room with no communication, and no idea what was happening, we were in complete darkness, we had no idea why we were in lock down, or how long we were going to be there or what was going on, so that was pretty scary.
The worst part was not knowing, thats what broke us down, and caused so much stress, every other person in the city knew what was going on except us! And that scares me.
But no one was hurt, we're all just shaken up, and glad that we were not alone in this, we experienced this as one, as an entire school, and i'm glad that we can all support each-other.
